horizontal viscosity coefficients

[amaltea]

Dear users,

I have problems with values for horizontal viscosity coefficients. I have defined the Smagorinsky option in the cppdefs.h and I changed the visc3d value in roms.in. However the results did not change.
Does anyone have information on how can I change this coefficient??

As a beginner, I would appreciate any help.

Regards,

If you want to tune your Smagorinsky parameterization, you will need to find out where it is actually coming from. Once you have compiled the code, do a grep of visc3d on your Build directory. If hmixing.f90 shows up, you will see that there is a SmagorCoef constant set in that file. It isn't picking up anything from ocean.in as far as I can see.
